Abstract: 696,115. Rolling. HYDROPRESS, Inc. Oct. 25, 1951 [Nov. 2, 1950], No. 24974/51. Class 83 (iv). In a tilting apparatus for rolling-mills having a set of gripping rollers which are movable relative to each other, the rollers are mounted in a common frame which is turnable about an axis parallel to the longitudinal axis of the bars to be tilted, and comprise at least one gripping roller which is rotatable about an axis fixed relative to the frame, and at least two oppositely disposed gripping rollers, each of which is rotatable about an axis pivoted on the frame, so that the gripping rollers can form together a triangle or triangles of contact for holding a bar during a turning movement of the frame. A substantially C-shaped frame 23 is mounted in a carriage 18 slidable on guides 17 on a fixed frame 16, being slidable transversely to the conveyer 11 under the action of a screw spindle 19 which meshes with a nut driven by reversible electric motor 27. The frame 23, which is rotatable within the carriage by means of a driven worm 26 engaging with the toothed periphery of the frame, carries a roller 28 on a shaft 29 which is fixed relative to the frame, and pairs of rollers 33, 35 carried on arms 32, 34, fixed at each end of shafts 30, 31. Each shaft is rocked by means of a fluid-pressure-operated rack 37, 42 which engages with a gear segment 36, 41 on one of the arms 32, 34 carried by the shaft, so that the position of the pairs of gripping rollers 33, 35 may be controlled relative to each other and to the roller 28 to grip between them bars of irregular cross-section, while frame 23 is tilted to the desired'angle and the carriage 18 is displaced laterally to align the tilted bar with the next roll pass. Since the gripping rollers are rotatable they continue to hold the bar in position as it is forwarded by the conveyer rollers 14 to the next roll pass. In a modification, Fig. 4, the support 54 for a rotatable frame 59 is vertically movable on its supporting carriage 51 by means of screw spindles 55 so that in its operative position the frame 59 is below the supporting surface of the conveyer rollers 14<SP>1</SP>.

Title: Discharging device for cigarette rod machines
IPC: A24C5/32
Filed: 1948-09-27
Abstract: 651,679. Pneumatic conveyers. DANK, H. Sept. 27, 1948, No. 25102. Convention date, July 12, 1947. [Class 78 (i)] [Also in Group VI] A discharging device for a cigarette rod machine is characterized in that the cigarettes are discharged pneumatically from the cutter tube. As shown, the cigarette rod is progressed along tube 1 and is cut into cigarette lengths by reciprocating cutter 2, the alternately long and short cigarettes passing into tube 3 into which air is blown through the side holes shown to project the cigarettes into either of compartments 4 or 7 furnished in the exterior of rotatable drum 6. The drum is rotated at such a speed that cigarettes fall alternately into compartments 4 and 7, the compartment 4 having abutment 5 and compartment 7 having abutment 8 laterally displaced from abutment 5, so that the two sets of cigarettes long and short are displaced one from another. The rotating drum carries round the cigarettes and discharges them on to conveyer 11 in two piles respectively 10 and 9. The air current thus enters into the side holes in tube 3 and passes through holes in abutment 5 and through holes 12 into fixed hollow member 16, and through holes 19 out into fixed hollow shaft 17. Compartments 4 and 7 are provided respectively with holes 13 and 14 to allow air to escape sideways and thus to slow up impact of the cigarette on the abutments. The pneumatic conveying movement may be assisted by a pair of oppositely rotating rollers introduced into tube 3 through slots therein and positioned parallel to the tube so as to engage the cigarettes and help them on. A fixed flap 15 and cover 22 retains the cigarettes in the drum.
